'JOHN'-PETTENGILIM JR., 0F LISBON, `NEVVI.H Atlldl'SHIRE, Letters PatentNo. 66,385, dated July 2, 1867 IMPRovnD csnooUPLINe;

To ALL WHOM 'I'riMAY coNcElm Be it knownthnt I, JOHN IEr'rENG'Itn,

1x.,of Lisbon, Grafton county, New Hampshire, have invented a new andimproved CarCouplinglg andIdo hereby declare that the following'is afull, clear, and exact descritti' tion thereof, which will enableotherssltilled` in the' art to makeand use thesame, referencebeing hadto lie' aecompanyiii'gdrawings, forming part of this'specilication, inwhich-.-

` Figure 1 is a longitudinal central section of 'my improvedcar-coupling.'

Figure'2 is a horizontal section of the same.' Similar letters ofreference indicate corresponding parte.

This invention relates to a. self-acting car-coupling, which is soarranged that the link 'will be held between` the elastic sides of thecoupling-box, so' that the link is prevented from rattling, and isalways'held firmly in any desired position. Provision is also made that'high and low cars can be coupled.. The coupling-pin rests upon a palletorhorizontal upper arm of an elbow-lever which is pivoted to the'coupling-box by spin which passes through thelower part of the verticalarm of said elbow-lever. IThe weight of -th'e horizontal arm and of thecoupling-pin keeps the lwhole lever forward; but as s oon as thelin'k'strikes any portion of the vertical arm of the lever, thesame'will be bent back, and the horizontal part be withdrawn. from underthe couplingpin,.

which willdrop through the link. As soon :xs the pin is raised again,and' 4the link withdrawn, the weight of the'horizontal armwill bring theelbow-lever again into the aforesaid positioni4 A represents acoupling-box, made of suitable' material, and of (the usual feint.Across the' front opening of the box is placed a bar, B, which dividesthe entrance into an upper and llower part, so that the links C willhave less play up and do'wn. The sides of thel box are open, and springsD D are arranged therein,` which are firmly secured to the rear endl ofthe box, their front ends forming elastic sides ofthe box.' )As isclearly shown .l in iigs. 1 and 2, these springs do not extend quite tothe; front end of the box, but leave a strong bumper frame in front. Thefaces of the springs D in the coupling-boxes may be covered with Indiarubber, leather, or other suitableelast'c material. E is anfL-shapedlever, of wblich the horizontal arm Aa is o'n top, and points forward,

as shown in the drawing. The vertical arm b of the lever is pivoted by apin, c, to the sides of the box A, theV said piu'passing through'thelower part of the arin b, andas near to therear edge of the same aspossible. The whole lever E will thus be madel to lean forward-*byitsown gravity, as shown in iig. 1, and the end of the arm will close thehole d in the pperpartfof the box A, as shown.- F is the coupling-pin,which rests upon the end of the arm a, 'and passes *through the hole d,as 'shown in iig. 1. When the link C is pushed into the box, it strikesthe erinb of the levergE, and throws it back," so 'as to release the pinF, which' will then drop down thronghthe link', as shown onthe-right-hand side of iig. 1. As soon as the pin is raised and the linkremoved, the arm-a will drop forward and close the holeI d again, asshown in the left-hand sideof iig. 1; The joint weight of the arm` a andpin will hold the' said ar'm a in position forward, so that no rattlingor shaking :notion of the car will be ablto swing the lever E back-anddrop the pin F' spontaneously. The springs D D clamp that end of thelink whichis in the box irn'ily, and prevent the same frorn movingsideways unless when turning the lcurve. -They will' then give as muchas necessary, and will at once resume their original position when thecurve is passed. They act as elastic cheeks 4for the sides of the box A,and hold the link in' any desiredposition.

j Having thus described my invention, what I claim as new, and desire toeec'ure'by Letters Patent, is

The'combination of the box A, link C, springs D, and elbow-plate E, withleach other, all made and oper ating substantially as herein4 shown anddescribed. l
